Carotid Endarterectomy (Cadaver) Meghan Robinson1; Laura Boitano, MD2; Samuel Schwartz, MD2 1Lake Erie College of Osteopathic Medicine 2Massachusetts General Hospital
Carotid stenosis is one of the leading causes of ischemic stroke worldwide. In the United States, nearly 800,000 strokes are reported each year, with ischemia accounting for 87% of them, and 15% traced to a carotid origin. Carotid endarterectomy represents an effective surgical treatment for carotid stenosis in preventing the risk of future ischemic stroke. This video-article demonstrates the surgical technique for carotid endarterectomy on a cadaver and discusses a typical case presentation of an individual who could potentially benefit from this procedure.
Current evidence supports the use of robotic surgery as a method of minimally-invasive treatment for adrenal masses. This article presents the case of a robotic adrenalectomy (RA) for an adrenal tumor. Upon examination of the extracted 1.5-cm specimen, it exhibited typical characteristics of aldosterone-producing adenoma, including a golden tan color, well-circumscribed borders, and surrounding normal adrenal gland tissue and fat. The detailed demonstration of this surgical procedure in the accompanying video provides a thorough understanding of the latest advancements in robotic adrenal surgery, offering comprehensive insights into the nuanced techniques and emerging trends in the field.
Tympanoplasty (Revision) C. Scott Brown, MD1; Alex J. Carsel2; Calhoun D. Cunningham III, MD1 1Duke University Medical Center 2University of Toledo College of Medicine
The tympanic membrane (eardrum) acts as a protective barrier between the middle and external ear, guarding the middle ear against infection. Additionally, it plays a crucial role in hearing by facilitating impedance matching between the air in the external canal and the fluid in the inner ear. Disruption of the tympanic membrane can lead to hearing loss, recurrent infections, and ear drainage. Common etiologies of perforations include infection and trauma. When perforations persist and cause symptomatic hearing loss or recurrent infections, surgical repair by an otolaryngologist becomes necessary. Although primary tympanoplasty has high success rates (75–95%), failures can complicate subsequent repair attempts. This case study presents a 61-year-old female who underwent two prior tympanoplasties without success. Dr. Cunningham demonstrates intraoperative decision-making and surgical techniques for repair in challenging cases.
This article present the case of a female patient in her early 20’s who was seen for follow up after 5 months of rehabilitation following surgical procedures to address instability in both the medial and lateral sides of her right ankle. This patient reported achieving an excellent outcome, and her subjective sense of significant improvement after rehabilitation was aligned with her physical exam and radiographic evaluation. This case documents the improvements made by the patient during the rehabilitation process and outlines essential steps to be performed by the practitioner in the clinical examination and radiographic follow up after surgery for ankle instability.
This video describes the surgical technique for an open duodenal resection and antrectomy, which was performed for a neuroendocrine tumor of the duodenal bulb. In this procedure, an upper midline laparotomy is first made, followed by mobilization of the distal stomach, duodenum, and head of the pancreas. Next is to Kocherize the duodenum, then ligate that right gastric artery and dissect the gastrohepatic ligament, followed by ligation of the right gastroepiploic vessels and taking down the gastrocolic ligament exposing the lesser sac. Once the structures are adequately mobilized, the first portion of the duodenum is dissected off of the head of the pancreas and transected with a TA stapler. The antrectomy is performed next, removing the specimen. For the reconstruction, a retrocolic end-to-side hand-sewn gastrojejunostomy was performed. This technique can be used for multiple indications, including peptic ulcer disease and other mass lesions of the antrum, pylorus, or duodenal bulb.
The ethmoid arteries, comprising the anterior and posterior branches, are integral vascular structures that hold immense significance in the realm of sinus and skull base surgery. Originating from the third segment of the ophthalmic artery, these arteries traverse through the medial orbit before passing through the respective ethmoidal canals and entering the ethmoid air cells. Understanding the anatomical significance and clinical implications of the anterior and posterior ethmoid arteries is paramount in ensuring safe and effective management of sinus pathologies and associated complications. Accurate preoperative assessment, appropriate surgical techniques, and a thorough knowledge of these vascular structures are essential for optimizing patient outcomes and minimizing the risk of adverse events during surgical interventions.
Patients who undergo longitudinal sleeve gastrectomy (LSG) may develop de novo or worsening of existing gastroesophageal reflux (GERD) symptoms, which include postprandial retrosternal burning, food refluxing, or dysphagia. Often patients with GERD following LSG present with a concomitant hiatal hernia. Workup serves to characterize a patient’s GERD disease burden by way of fluoroscopic upper gastrointestinal (UGI) series, pH studies, manometry, or esophagogastroduodenoscopy (EGD). Treatment first involves medical management with lifestyle modifications followed by use of pump inhibitors (PPIs) or Histamine H2-receptor antagonists (H2 Blockers or H2B). If GERD symptoms remain intractable to medical management, surgical intervention can be pursued.
Historically patients would undergo a conversion to a Roux-en-Y gastric bypass (RYGB). New data demonstrate comparable outcomes regarding GERD symptoms and improvements in anti-reflux medication use in patients status-post LSG who undergo ligamentum teres cardiopexy with hiatal hernia repair. This article describes a robotic ligamentum teres cardiopexy with hiatal hernia repair in an adult patient who previously underwent LSG and was experiencing intractable GERD symptoms despite lifestyle modification and optimization on anti-reflux medications.
Intraperitoneal Mesh Repair for Incisional Hernia William B. Hogan1; Yoko Young Sang, MD2; Shabir S. Abadin, MD, MPH3 1Warren Alpert Medical School of Brown University 2Louisiana State University Shreveport 3World Surgical Foundation
Incisional hernias remain an important postoperative complication of any procedure involving a laparotomy incision. Although most incisional hernias remain asymptomatic, incarceration and strangulation are emergent complications requiring prompt diagnosis and intervention. Mesh repair has become widely favored over simple suture repair of abdominal fascial defects in recent decades, though recurrence of incisional hernias remains high. Despite the advent of laparoscopic approaches to hernia repair, open approaches are utilized when numerous adhesions are encountered, laparoscopic access is unsafe, or when laparoscopy is not readily available. We present an open surgical repair of a large incisional hernia involving the abdominal midline and parastomal site in a woman with a history of laparotomy and colostomy with a subsequent reversal for a perforated colon.
